How do you back up contacts and text messages with the Phantom MX3 phone?

1, MX3 Mobile phone use is the flyme3.0 system, we in the mobile phone to open the "Settings" button click to enter.

2, then we in the setting of the account to click on the FlyMe account login (this is the Phantom account if we do not have to connect according to the prompts)

3, login up I can choose the phone to back up the data to back up, specifically we define it as shown in the picture.

Okay, well, then, if your cell phone is back to the factory, or if you're going to switch to another one, we can connect to the cloud through the Phantom account and then sync it up.
